Predictive Method for Controlling a Blood Processing System
First Claim
1. A method for controlling a density centrifuge blood processing system for separating fluid components, said method comprising the steps of:
- performing a first measurement of an operating condition of said blood processing device corresponding to a first time;
performing a second measurement of said operating condition of said blood processing device corresponding to a second time;
analyzing said first and second measurements of said operating condition using a predictive data analysis algorithm, wherein operation of said predictive data analysis algorithm generates a predicted operating condition of said blood processing device corresponding to a selected future time;
comparing the predicted operating condition of said blood processing device corresponding to the selected future time to a desired operating condition; and
adjusting at least one setting of said blood processing device based on said comparison of the predicted operating condition of said blood processing device at said future time and the desired operating condition, thereby controlling said blood processing device.

Abstract
The invention relates generally to methods of monitoring and controlling the processing of blood and blood samples, particularly the separation of blood and blood samples into its components. In one aspect, the invention relates to optical methods for measuring two-dimensional distributions of transmitted light intensities, scattered light intensities or both from a separation chamber of a density centrifuge. The method may include performing first and second measurements of an operating condition; analyzing the first and second measurements using a predictive data analysis algorithm; comparing the predicted operating condition to a desired operating condition; and adjusting at least one setting.
